' Specification of Letters Patent.

Application filed I anuary 29, 1814. Serial No. 815,1!19.

To all whom it may. concern Be it known that I, JAMES K. DIAMOND, a citizen of the United States of America, ne,-. siding at Errand Rapids, the county of Kent and State of Michigan, have invented certain new and useful Improvements. in Tools for ClenchingBelt-Fastenrs; and I do hereby declare the followingto be a full clear, and exact description of the invention, such as will enable others skilled in. the art to which it appertains to make use the same.

This invention relates. to improvementsjn tools for clenching belt fasteners, and more.

particularly to means for alinin g the fasteners insuch devices as described in my Patent No. 1,060,746 issued May 6,1913, and its object is toprovide in a tool of this class means for holding the fasteners which will be simple and effective in operation, and'to.

provide the device with various novel fea-. tures of construction and operationv as hereinafter more fully described and particu-v larly pointed out in the claims, reference being had to the accompanying'drawings, in.

which I Figure 1 is a plan view of a device em.- bodymgr this invention with parts broken away; ig. 2 is a transverse sectional ele-. vation ofthesame on the line.22.of Fig. 1; Fig. 3 is a fragmentary section on the: line 3-3 of Fig. 1; Fig. 4 shows'the device in transverse section p to operate, uponthe fasteners and Fi 5. shows the deviceclosed by the vise and t fasteners clenched upon the belt.

Like numbers refer to like parts in all of the figures.

The device comggri'ses a base'1,the upper surface of whichrms one of the clenchln dies, the said base memberbeingprovide with a groove on rabbet extending longitudinally of its rear edge, in which a. receiving member 2 is slidably mounted. Guide. pins 3-extend through the said receiving-memberand are supported. 'at their respective ends by the base 1 and a plate 4 secured-to the i rear; edge.

of said base, and springs 5 sur-. rounding said pins 3.yieldably force the said member toward base.

The 'receivin member 2 projects above the. surface oft fi fiti Rmvidedj: 1n

laced betweenthe jaws.

the. forward, edge of the.

its forward edge with a. series of transverse grooves. 6 at regular intervals to receive the middle curved portion of the respective belt fasteners. A vertically slidable retainin bar 7 is located near the forward edge 0 the base 1 and is normall raised to project above the surface of the base by springs 8, but may be depressed under pressure to recede fiush with the said face. This bar 7 is provided in its side opposite the receiving member 2 with a series of recesses 7- corresponding to the recesses 6 in the said; mem, ber, these recesses being preferably alternately deep and shallow to receive the alternately arranged ends of the belt fasteners which have legs of unequal length.

The device is provided with an alining member 9. mounted on the receiving member 2 and provided with a series of rejections to enter the grooves in the said receiving member to engage the fasteners therein and the said alining member is retained on the receiving member by screws 10 which pass therethrough and is yieldabl pressed downward by springs 11 beneat the heads of said screws.

A releasing screw 12 has a bearing in the plate t at the back of the base, is screwed into the body of the receiving member 2 and provided with a knurled head by which it. may be manually turned to draw the said re: ceiving member away from the bar 7, con1- pressing the springs 5,

The pivoted clenching die 13. is provided on its. respective ends with arms 14. which.

embrace the respective ends; of the receivingmember 2 and are slotted at right anglesto the clenching face of the die, and ivot, screws 15 extend through said slots. an piv-v dtally connect the said die to the receiving have been properly arranged in the device as shown in Fig. 2 the screw 12 is turned-to allow the receiving member 2 to moveforward under tension of the springs '5 until 5 stopped by engagement of the bottoms of the recesses 6 by the curved portions of the fasteners. During this movement the projections on the alining member 9 have engaged the fasteners 18 and pressed them 10 firmly against the clenching surface of the base and retained them in this osition under tension of the springs 11. he pivoted die 13 is now moved downward until its clenching surface engages the upper legs of 15 the fasteners 18, and the device is then placed between the jaws 17 of an ordinary machinists vise being supported by the shoulders 16, as illustrated in Fig. 4. The

end of the belt 19 may now readily be placed v 20 between the open ends of the fasteners 18 and adjusted to the proper depth by enas the jaws 17 are forced together the pivoted die 13 will be moved toward the base 1,

26 clenching the fasteners 18 upon the belt in roper alinement. The die 13 by virtue of its slotted connection with the receiving member 2 is adapted to move bodily toward or from the base 1 and hence automatically 30 adjust itself to different thicknesses of belts andthe retaining bar 7 when engaged by the belt will yield suflicientlyto permit the fasteners 18 to be properly clenched. The device is shown at the completion of the 0p- 86 eration in Fig. 5. g 1
